Numerical prediction competition is also conducted together with the tests. The results of the experiments and numerical simulations are published on the internet, which can be freely downloaded by researchers and engineers. The design, the experimental process and the test results of the 2 key beam column joints and 4 key columns are introduced.Keywords: Wenchuan Earthquake; RC frame structure; collapse; reinforced concrete; numerical simulation*国家自然科学基金项目（90815025，51178249，51178250），国家科技支撑计划课题（2009BAJ28B01），工程院重大咨询项目（2010\|ZD\|4），教育部新世纪优秀人才支持计划资助 （NCET\|10\|0528）。作者简介：陆新征，博士，副教授，Email：luxz@tsinghua.edu.cn。参考文献［1］ 陆新征, 叶列平, 潘鹏, 等. 钢筋混凝土框架结构拟静力倒塌试验研究及数值模拟竞赛Ⅰ：框架试验［J］. 建筑结构, 2012，42（11）：19\|22,26.［2］ 中国建筑学会建筑结构防倒塌专业委员会. 钢筋混凝土框架结构拟静力倒塌试验研究及数值模拟竞赛Ⅲ：模拟结果分析［J］. 建筑结构, 2012，42（11）：27\|30.
